we are trying to improve the distribution of SixTrack tasks. If your host could process more tasks but during the project update you don't receive any, can you let us know and send us your client logging report? Please continue the thread "SixTrack Tasks NOT being distributed" opened by Eric here:http://lhcathome.cern.ch/sixtrack/forum_thread.php?id=4324
so that we can collect all the issues in only one place. In this way, we could try to better tune parameters controlling the distribution of tasks on the server side.

The origins of the most crunching problem is a driver problem.
The computer need an update by installing the virtual box 5.1.26.
If the computer has this driver, then the most problems are solved and the computers runs quiet.
An update of the Nvidia driver is also recommnded for the other projects.
Since i made that operations the computers are OK

P.S.: I am now running under Gridcoin pool.com-2 with 3 computers with 2 I7 and 1 I5

There are many problems we are trying to address, at different levels (eg failures in cgi, failures in upload/download, non-optimal user settings, non-optimal server settings, ...). Moreover, please keep in mind that SixTrack jobs do not need virtual box (contrary to apps from the LHC experiments), as we distribute executables dedicated to the most common platforms/architectures/CPU flags.
